Hair assessments have emerged as an effective method to identify drug and alcohol consumption. Hair captures a prolonged history of substance use by enclosing biomarkers within the fibers of the growing strand. When collected near the scalp, hair offers a detection window of up to around 90 days for alcohol and other substances. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.
A 1.5-inch sample comprising roughly 200 strands (equivalent to the width of a #2 pencil) closest to the scalp provides 100mg, the preferred volume for screening and confirmation. For EtG, additions, and/or assessments exceeding 10 panels, a 150mg specimen is advisable. It is suggested to weigh the specimen using a jeweler's scale. Should scalp hair be unavailable, an equivalent amount of body hair may be gathered. When referring to head hair, it specifically pertains to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning comprises the initial intake of a specimen into a laboratory's system. This step includes verifying proper sealing and shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any data input not covered by an electronic chain of custody system.
Screening encompasses a preliminary evaluation for the presence of drugs. While Screening serves as a cost-efficient means to eliminate most samples from drug use suspicion, any positive results necessitate confirmation to be valid in legal proceedings. Samples marked as presumptively positive in Screening must undergo secondary confirmation.
In the event of a presumptively positive result during Screening, more hair is extracted from the original specimen and readied for Extraction. In this phase, drugs are extracted from hair at much lower concentrations in comparison to alternative methodologies (e.g., urine or oral fluid), rendering hair drug analysis the most challenging procedure to conduct.
Confirmation of any positive outcome from screening is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples reported as presumptively positive are cleansed before confirmation, as needed. The entire laboratory workflow from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and in line with accreditation to ISO / IEC 17025 standards.
